3 Claims.

This invention relates to container closures applicable to bottles orcans or the like, and has for its primary object improved means foreasily Aand readily controlling the outlet of the conltainer indispensing materials therefrom.

A further object of the invention is to provide a container closurewhich is of simple and economical construction, which positively sealsthe container when the closure is in closed position, which is positivein operation and which can be easily and quickly assembled.

Still further, the invention aims to provide novel means for latchingthe closure in either open or closed position and to also provide a`Z`container composed of a minimum of parts which may be marketed at alow cost.

Still further, the invention aims to provide a device of this typewherein the closure is moved to open position by sliding thereof axiallyof the Ycontainer and to further provide for substantially circulardispensing of the material in use.

The invention has further and other objects which will be set forth andmanifested in the course of the following description.

In the drawing:

Figure 1 is a side elevation of the invention,

the container being shown in fragment;

Figure 2 is a section on line 2-2 of Figure 1;

Figure 3 is a section on line 3--3 of Figure 1;

Figure 4 is a view similar to Figure 2, showing the parts in dispensingposition.

In proceeding in accordance with the present invention the container hasa neck 1 which may be of cylindrical form and is provided with an insetportion 2 from which a dome 3 extends, the latter being tapered orinclined as shown at 4 and provided with dispensing orces or apertures5. The dome preferably has a at top 6 as shown. The closure 7 slidesaxially of the dome and is of ring-like form and has an inclined outerportion 8 which, when the parts are in the position of Figure 2, closelyengages the inclined part 4 of the dome so as to effectually seal thecontainer.

i The closure is formed with a circular outwardly extending flange 9which latter is preferably rolled to provide a bend 10, the latteraffording a circular finger engaging member by means of which theclosure can be slid from the position of Figure 2 to that of Figure 4,and vice versa. It will be noted that the flange 9 seats on thehorizontal part 11 of the inset part 2 thereby to additionally seal thecontainer against the ingress of air or moisture or the like. The dome 4is provided with a pair of spaced inwardly struck (c1. zal-62) teats 12forming keepers for engagement with corresponding teats 13 that arestruck out from flaps 14 that are formed integral with the closure '7and are located at diametrically opposite points on the latter. Theseflaps constitute catches that are flexible and which as shown in Figure1 are formed by slits formed in the closure. For the purpose ofpreventing rotation of and for also restricting sliding movement of theclosures relative to the dome, the latter is provided with elongatedinwardly struck portions 15 which provide channels in which inwardlystruck teats 16 on the closure 7 are freely slidable and which uponengagement with the ends of the channels provided by the elongatedinwardly struck portions 15 restrict sliding movement of the closureaccordingly.

In operation it will be seen that upon movement of the closure from theposition of Figure 2 to that of Figure 4 the openings or apertures 5will be uncovered whereby the material will egress therethrough andengaging the inclined parts 8 of the closure will be dispensed in asubstantially circular formation.

What is claimed is:

1. In combination with a container neck having an inset portion providedwith a circularV dome that has a tapered portion which is apertured andwhich has a flat closed top, a slidable closure on the dome having anopen top and a tapered portion engageable with the tapered portion ofthe dome to seal the apertures of the latter, said closure having aflange engageable with the inset and having a circular finger-engagingpart on the flange, a vertically channeled part formed in the dome, amember carried by the closure and extending into the channeled part toprevent rotary movement, and to restrict sliding movement of theclosure, a flexible member carried by the closure and having aprojection, and keepers carried by the dome to engage the projectionwhereby to latch the closure in both open and closed positions.

2. In combination with a container neck having a dome formed with anouter tapered part which is apertured and with a closed outer end, anaxially slidable closure on the dome having a tapered part closelyfitting that of the dome and having an open outer end, means to preventrotation of and to restrict sliding movement of the closure on the domeincluding a channeled part on one of the last two named elements and aprojection on the other of the two said elements engaged in thechanneled part, a flexible catch on the closure having a projection andkeepers on the dome for engagement with the projection of the catch.

3. In combination with a. container neck having a, dome formed with anouter tapered part which is apertured and with a. closed outer end, anaxally slidable closure on the dome having a. part closely fitting thatof the dome and having afi iloi
